电磁波

The interference image spectroscopy coupled with the Doppler effect of electrical and magnetic waves are employed to measure the natural airglow and auroral visible emission lines in the upper atmosphere.

以上层大气中的气辉为被探测源，利用干涉成像光谱技术和电磁波的多普勒效应对上层大气风场进行测量，分析和计算了大气风场的速度和温度，并就被探测源和探测器之间的相对速度与其连线成任意角时的情形进行了讨论。

In the first chapter, the efforts made by the human beings to utilize electromagnetic resources were reviewed, the physical mechanisms underlying Cherenkov free-electron lasers expounded and the research activities in this field, both in and out of China, summarized.

第一章回顾了人类在开发利用不同波段的电磁波资源方面所做的努力；阐述了契伦柯夫自由电子激光的互作用机理并详细介绍了国内外这一活跃领域的研究状况。

F region is one of the most important regions in the ionosphere. The night-time irregularities in this region can affect nearly all-frequency radio waves propagating through them.

电离层F区是电离层最主要的区域，尤其是其中的不规则结构，导致几乎所有波段的电磁波产生幅度和相位的闪烁。

In this paper,it is studied that the angular spectral method for electromagnetic wave propagation is equivalent to Huygens principle .

证明了平面电磁波传播的角谱法与惠更斯原理是完全等效的。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
